JUDSON COOK, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF '10 THOMAS CRAWFORD, JR., 0]? PHILADELPHIA, PENNSYLVANIA.

METAL CORNER-BAR.

To all whom it may concern:

Be it known that I, J UDSON (3001;, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metal Corner-Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in metal corner bars or strips for concrete curbs, whereby the same will be supported in a firm and rigid engagement with the curb.

One object of my invention is the provision of a bar so constructed as to prevent all longitudinal movement of the same, by providing it with a series of pockets or recesses which, when the corner bar is embedded in the curb, become filled with concrete, thereby preventing all movement.

Another object of this invention is the provision of a bar adapted to be securely held within the curbing against lateral dis placement, and of such construction as to prevent chipping of the curb, caused by the contact of the wheel of a heavy vehicle thereagainst.

Still another object of my invention is to provide a corner strip or bar that will be comparatively cheap to manufacture, simple of construction, and easy of application.

With these and other objects in view, this invention resides in the novel features of construction and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which the figure is a perspective of my invention applied.

Referring to the drawings by characters of reference, the numeral 1 designates generally my improved corner bar, which is substantially T-shaped in cross section, consisting of a web 2, one end of which is enlarged to form a head 3, the outer face of which is convexed to present a smooth corner for the curb. The said enlarged head is provided on the under face thereof, adjoining the web 2, with a series of alternately arranged pockets or recesses 4: and raised blocks 5, which Specification of Letters Patent.

extend the entire length of the bar. These pockets and blocks are so arranged that the pockets on one side of the bar are opposite the raised blocks on the reverse side thereof, so that the bar will be of equal strength throughout its whole length. The end of the web 2, opposite the head 3, is provided with corrugations 6, the bearing faces 7 of which form an anchor to lock the bar into the concrete. This construction also serves to stiffen the web, thus allowing it to be made of a smaller amount of material than would otherwise be necessary.

It will be seen that when the bar is embedded in the concrete it will be securely locked therein, the pockets and blocks preventing any longitudinal movement, while the corrugated edges prevent any lateral movement.

' Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a cement curb, a metallic corner bar comprising a web, an enlarged head on one end of said web, having pockets and raised blocks provided on the under faces thereof adjoining said web, said pockets and blocks adapted to prevent longitudinal movement of the bar.

2. In combination with a cement curb, a metallic corner bar comprising a web, an enlarged head on one end of said web, having pockets and raised blocks provided on the under faces thereof, said blocks and pockets arranged alternately the entire length of the bar, and the pockets on one side of said bar being opposite the raised blocks on the other side thereof.

3. In combination with a cement curb, a corner bar comprising a web, an enlargement on one end of said web, having pockets and raised blocks provided on the under faces thereof adjoining said web, the end of said web opposite to the enlarged head being corrugated to form an anchor, as and for the purposes hereinbefore disclosed.

In testimony whereof I afiix my signature in presence of two Witnesses.
